Abstract

A liquid display device comprises a backlight unit, a display panel and a first bezel containing the backlight unit and the display panel. At least one sidewall of the first bezel is formed with an extension portion in an arc shape extending toward a middle portion of the first bezel. A free end of the extension portion is disposed opposite to a sidewall of the display panel. The display panel is disposed in the first bezel. The extension portion helps to form the smooth transition between the display panel and the first bezel. The cover glass disposed on the liquid display device is not required. The complex cover glass polishing process is eliminated. The limitation of the 2.5D display screen only applied in the application of the small-size display screen is also eliminated. The disclosure reduces the production cost and increases the application range of the display screen.
